Question on aging Love Sword

[zmrram 0]

- Today I got myself a Love Sword, to make it look nicer I'm decided to age it. However, for some reason it's impossible to mature after I aged it. Even at the lowest ++. My MS is 128 and I use the Love Sword in Ancient Dungeon 2 but it doesn't mature. Can someone tell me why?

 

Thanks

Swords only age when dealing critical hits.

Love Sword has zero Critical, so, at early stages, you'll gotta use mature stones.
